How to Know if You Should Rewire Your House?

Key Takeaways

• Electrical systems age over time and can become potentially unsafe. Modern demands on electricity have grown, and outdated systems may not be equipped to handle current needs.

• Regular inspections by professionals, especially for older homes, are crucial. In the UK, homes should be inspected every 10 years, and rented properties every 5 years.

• When considering rewiring, it's imperative to hire professionals for safety, code compliance, efficiency, proper tool utilisation, and future-proofing your home with updated systems.

Electrical systems form the heart of our modern homes, powering everything from our essential appliances to our luxury gadgets. 

Ensuring they function efficiently and safely is paramount. But like every other component of a home, electrical systems age. As they do, not only do they become potentially unsafe, but they may also struggle to keep up with the burgeoning demands of contemporary living. 

Over the decades, our reliance on electricity has grown, as have the standards for safety and efficiency. 

So, how do you know when your house needs a rewiring? Let's find out.

How Can I Tell if a House Needs Rewiring?

Understanding when your house needs rewiring is a mix of awareness and vigilance. 

Modern homes are equipped to handle a plethora of electrical devices. However, older homes, which might have been top-of-the-line during their prime, can lag behind in terms of safety and capacity. 

Outdated wiring can result in inefficiencies and, in some instances, potential fire hazards.

Regularly inspecting your electrical panel, looking out for any discoloration on sockets, or even frequently tripped breakers can hint towards an outdated electrical system. 

Further, if your home still employs old-fashioned fuses instead of modern circuit breakers, it's an immediate indication of an outdated electrical system.

The Importance of Regular Electrical Inspections

It's beneficial to have a licensed electrician inspect your home's electrical system every few years, especially if it's an older home. 

They can identify potential hazards, suggest upgrades, and recommend whether rewiring is needed. 

Regular safety inspections can prevent problems before they become significant issues, ensuring your home remains safe.

For home owners it is recommended that they have electrical inspections carried out every 10 years. Landlords should schedule them every 5 years for their rented properties.

Signs Your House Needs Rewiring

1. Frequent Electrical Surges: These can be caused by various reasons including lightning strikes, faulty appliances, or poor electrical wiring in the house.

2. Dimming or Flickering Lights: This may indicate that your circuit is overloaded.

3. Overheated Outlets or Switches: If they are hot to touch, there's likely an underlying issue.

4. Burning Smell: An obvious red flag, any burning or acrid odour from outlets or switches requires immediate attention.

5. Frequent Breaker Trips: While breakers are designed to trip for safety, frequent trips can indicate an overloaded circuit or a short.

When Should You Rewire a House?

Ideally, consider rewiring during times of major renovations. Walls will be opened, making the process less invasive. If you've recently purchased an old home, it's wise to have an electrician assess its wiring. 

Further, if you're adding substantial new electrical appliances or converting areas like attics or basements, it's worth checking if your current system can handle the additional load.

How Often Should You Rewire a House in the UK?

In the UK, the general recommendation is that a house should be rewired every 25 to 30 years. 

However, this doesn't mean every home will need rewiring after 30 years. 

As alluded to above it's essential to get an electrical inspection every decade or if you notice any of the signs mentioned earlier.

Economic Benefits of Rewiring

Rewiring isn't just about safety. A home with a modern, efficient electrical system is more appealing to potential buyers. 

Additionally, some insurance companies may offer lower premiums for homes that have been recently rewired, recognizing the reduced risk of electrical fires.

The Importance of Hiring Professionals for Rewiring Work

When it comes to the intricate and potentially hazardous task of rewiring a home, relying on professional expertise isn't just a recommendation-it's imperative. Here's why:

1. Safety First: Electricity is not to be trifled with. An incorrect installation or a missed step could lead to severe electrical hazards, including fires, electrical shocks, and other dangers. Professional electricians have the training and experience to handle electricity safely, ensuring that all work meets the latest safety standards.

2. Ensuring Code Compliance: Electrical codes exist for a reason-they set the standard for electrical safety. A professional will be familiar with local, regional, and national electrical codes and will ensure your home's wiring is up to par. Non-compliance can lead to fines and could even jeopardise the validity of your home insurance.

3. Efficiency and Cost Savings: While hiring a professional might seem costly upfront, in the long run, it can save you money. Amateur mistakes or shortcuts can lead to higher energy bills, damaged appliances, or the need for future repairs. Professionals will ensure the job is done right the first time, preventing costly future issues.

4. Access to the Right Tools and Equipment: Rewiring a house requires specific tools and equipment, many of which are specialised for certain tasks. Professional electricians come equipped with everything they need to tackle the job efficiently, ensuring that the wiring is not just safe but also neatly and properly installed.

5. Warranty and Peace of Mind: Most professional electrical service providers offer a warranty on their work. This not only reflects their confidence in their skills but also provides homeowners with peace of mind. Should anything go awry post-installation, professionals will address and fix the issues, often at no extra cost.

6. Knowledge of Advanced Systems: The modern home is evolving, with many households now incorporating smart systems, home automation, and energy-saving solutions. A professional electrician will be abreast of these advancements and can offer guidance on how best to integrate such systems during the rewiring process.

FAQs

How much does it cost to rewire a house?

The cost of rewiring will range from £2000 for a small flat to £9000+ for a larger house (5 bedrooms or more).

Does a 1970s house need rewiring?

Houses from the 1970s often come with wiring systems that, while cutting-edge at the time, may now be outdated. Rubber cables, a common feature in the '70s, can degrade over time, making them unsafe.

It is highly recommended to have a professional assess the state of the wiring in homes of this age. 

Is it worth repairing a 20 year old boiler?

By the 1980s, there was a transition in wiring practices and materials. Though homes from this era might fare better than their 1970s counterparts, it's still worth having a thorough check, especially considering the nearing 40-year mark, well beyond the 25-30 year standard. 

How long does the rewiring process typically take?

The duration of a house rewiring project varies based on several factors, including the size of the house, its age, the complexity of the electrical system, and any obstacles or challenges that may arise. 

On average you can expect the process to take between 1-4 weeks depending on the aforementioned factors. 

Final Thoughts

Ensuring that your home's electrical system is safe and efficient is more than just a task - it's a responsibility. 

It safeguards your family, enhances the longevity of your appliances, and can even save on energy bills. 

Rewiring might seem daunting, but the peace of mind it brings is invaluable. If your home hasn't had an electrical check in the past decade or if it's showing signs of strain, now might be the time to seek expert advice.
